GEORGE O. HERB-ICE, OF AUCKLAND, NEWZEALAND.

OIL-CUP.

SPECIFICATION forming part of Letters Patent No. 247,057, dated September 13, 1881.

Application filed August 17, 1881.

To all whom it may concern Beitknown that I, G. CHARLES HERRIOH, of Auckland, New Zealand, have invented a new and useful Improvement in Oil-Oups, of which the following is'a specification.

My invention consists in a novel construction, arrangement, and combination of an oilcup and a valve and devices pertaining to the same, whereby the oil is supplied to the hearing intermittently, as hereinafter particularly described. 4

The accompanyingdrawing represents a vertical sectional view of my invention.

A is the oil-cup, which is of cylindrical form, and is provided with a screw cap or cover, B. If desired, a leather washer, I), may be interposed hetween the cup and the cover to render it air-tight. I 7

At the bottom of the oil-cup is an extension or neck, a, which is internally screw-threaded to form a socket for the reception of a plug, (3. This plug is provided with a thread, 0 for engagement with the socket, and another thread, a, for engagement with a threaded socket or recess in the bearing to which the oil-cup is to be applied.

In the center of the plug 0 is a longitudinal bore extending the entire length of the plug, and in the bottom of the oil-cup is an orifice of corresponding size and in line with the bore of the plug. In this bore and this orifice works a rod or stem, d, which is small enough to al- (No model.)

low oil to flow around it, as hereinafter described. The stem 01 carries a piston,D, which works, after the manner of a puppet-valve, in a chamber, E, formed by the space between the bottom of the oil-cup A and top of the plug 0.

The cup being applied to the hearing by insertin g the threaded portion 0 in a socket provided for it, the piston or puppet-valve Drises and falls by the motion and vibration of the machinery, and thus allows the oil to flow intermittently from the cup around the piston and stem and down through the bore of the plug to the hearing.

If desired, the valve-stem d may extend below the bottom of the plug, as shown,so as to touch the shaft which works in the bearing; and in some cases there maybe projections on said shaft to strike the stem at regular intervals and insure a degree of uniformity in the
